Be it known that we, SILAS R. DIVINE, of

f Loch Sheldrake, in the county of Sullivan and 'State of New York, and ADDISON Q. RAND,

5150f the city, county,and State of New York,

I Shave invented an Improved Method of Preqx paringCartridges for Blasting and other Pur- ;jposes; 'of'which the following is a full,- clear,

- "J, andexact description, reference being had to 10, the accompanying drawings, forming part of w this specification.

,The object of our invention is to facilitate ;,.the preparation for use of cartridges composed of two ingredients, one ,of' which is a r solid-and the othera liqnid'substance, which,

. gather; combined .hyflzheabsorption Ely "and 'eq'ualdistribution throughout the mass of the solid of the liquid in proper proportion,'con- I 'stitutes a high explosive -compou,nd*-as, for

zofexample the compound for whichIi'etters Pat ent No. 243,432 were granted June 28,1881, 0n the application of Silas R. Divine, in which the solid ingredient is .chlorate of potash or fits equivalent and the liquid ingredient is ,nitro-benzole' or its equivalent.

Ourinvention relates more particularly to a an improvement 'uponv the art of blasting, whichisdescribed and claimed in Letters 1370. 243,433, granted June 28, 1881, on due application; and it consists intaking thecartridge-shells, composed of porous'material-such as cloth the solid ingredient of the 'compoundand, first, submerging them .in a bathof the liquid ingredient fora certain predeterminedspace of time, andonlyuntil there shall have been ingredient of the cartridges prior to explodd cartridges, differing 5o Figs. 4, 5, and 6 represent cross sections of the Application filed February 10, 1883.

and show the envelope or casing of the cartridge and the contained solid ingredient, respectively, prior to submergence inthe bath of the liquid ingredient immediately after withdrawal from said bath, and: when theabsorbed liquid has become equally distributed throughout the solid ingredient; and Figs. 7, 8, and9reprcsent cross-sections of the larger cartridge under respectively similar conditions.

Herctofore in preparing cartridges, for use as in blasting operations, composed of a solid ingredient-such as chlorate of potash-and a smaller cartridge seen in Fig. 2,

liquid ingredient-suc'h as nitro-benzole.-the

porous cartridge-shells. containing the solid been in theliquid ingredient.-

to the duration of the immersion, and have been subsequently wrung out or otherwise manipulated to expel the excess of liquid with which they have become saturated, in orderto secure the proper relative proportions. in each cartridge of the two ingredients; or, each. cartridge has been openedat one end and the proper proportion .of the liquid ingredient has been introduced by pouring it from a package or bottle'con-' tainingonly the definite and designated quansize of cartridge; or the two ingredients have been initially mixed in proper proportions in a suitable vessel, and the compound'thus constituted has been introduced into the cartridge- "oases.

'Ourdcscribed invention is an improvement in convenience of handling and accuracy of results attained overthe methods heretofore em jf ployetl..

' carrying out'ohr invention we-take the cartridge-shells composed ofporous materiale I such as cloth or paper-andfilled with the solid 0 ingredients, preferably in a crushed or pow-'- cred state, and submerge them in a bath of the liquid ingredient. I To accomplish this, 'we find-it preferableto provide aperforated 'recep l tacle-such as an open tile, as shown at A, in

as seen at B, to contain the bath of the liquid,

and adaptedto receivewithin it the basketA.

Thusthe basket A, being grasped'by the bail, roo

may with its contained cartridges be readily, lowered 'or dipped into. the bath and the eartridges quickly and effectively submerged in the liquid. The cartridges containing the solid ingredient should be submerged in the bath for such a. definite space of time only as will, "secure the absorption qflthe proper propo'r- 'tion of the liquid ingredient relatively to the quantity of the "solid ingredient of each carro'tridge, so that When'said absorbcd liquid be- ,comes equally'distributed throughout the mass r of the solid thei'e'willlbe constituted in the:

- cartridge the proportions in which the ingre dientsof the compound will combine most cf 1 5' ,fectively'a's an explosive. I i r v g We find thatwhen chlorate of ,potashis-usedi as the solid and nitro-benzole asthe liquid: the .proper proportions to this end, as stated 'inthebefore-referred-toLetteis'Patent-mainei 11y, from three to four, or four and one-sixth parser the solidto one; art-of the liq uid-- 'iv'i'll be secured in cartri ges by subme'rgi'ng "them during acertain length'of time relatively tothir'diameters,asfollowsz Submer'ge acar- '25 'tridge of about one andon'e-fo'iztth inch di-' 'ameter during-aboutthree seconds; a'c'artridge v of about one and one-l1alf inch diameter 'dnring about 'four seconds; a cartridge of about one and. three fon'rths inch diameter duringg 3'0 abo'tit'five seconds, and a cartridge of about:

"two inches diameterdu'r'ing about'six seconds.

' jmrtfi those fs 'ted should, it is obvious, be sub lessgperioa of time, and reference shouldalso be imam the fluidity of the liquid. I

When the cartridges are submerged, the

porous envelope thereof and that portion of the mass of the'contained solid lying next 'to o the 's'aid'envclope will absorb the liquid. and

during the time designatedfor the submeri gen'cerelatively-tothediamcterofthecart-ridge,

'as set forth, the envelope and that portion of the solid immediatelycontiguous thereto will 4 5 absorb the proper or desired proportion of the liquid. In cartridges of difi'erent diameters this absorption will, owing to the relativelyvarying periods of time, as specified, extend more or less'in'to the portion of the mass of the [cartridge contiguous to the envelope; 'Thus in a larger cartridge submerged for a longer time the absorption will extend somewhat further inward than in a smaller cartridge's ibmcrgod for lessor time This is 1 5 fully illustrated i" Figs. 4- ztnd 7, are tridges o'f di'flbrcnt "mgs, where, in
